Abstract This article presents the results of the study of the bottom sediments of the meromictic Lake Doroninskoe. For the study, the method of spore-pollen analysis was used. The record showed that during the accumulation of 65 cm of the sediment layer in the Chita-Ingodinskaya depression, pine and larch predominated along the ridges, with steppe and meadow associations in the lower parts of the depression. According to regional correlations, the distribution of light-coniferous-taiga vegetation in Transbaikalia occurred as early as the Middle Holocene, and it did not undergo cardinal changes until modern times. According to these data, sediments may have accumulated during this time period.

Algae that inhabit extreme environmental conditions are often capable of synthesizing and storing unique biochemical inclusions. The diatom alga Nitzschia sp., strain Z-6, isolated from the meromictic Lake Shira, under conditions of nitrogen starvation, is capable of accumulating rare PUFAs (polyunsaturated fatty acids) that may be useful for biotechnology.
